Abstract

The invention belongs to the technical field of blast furnace distributing device cooling, and relates to a mixed cooling type distributing device. The device comprises a distributing device box body and a rotating cylinder body rotationally connected with the distributing device box body, a central throat pipe is arranged in the rotating cylinder body, and the central throat pipe is fixedly connected with the distributing device box body; the central throat pipe is sleeved with an intermediate cooling device for cooling the central throat pipe and the rotating cylinder body; the intermediate cooling device is fixedly connected with the distributing device box body and is arranged between the central throat pipe and the rotating cylinder body; and an aerial fog cooling device for cooling the bottom area of the rotating cylinder body is arranged at the bottom of the distributing device box body. By adopting a mixed cooling mode, high-pressure water cooling can be realized, the cooling efficiency is high, the problems of water leakage, easiness in scaling, low cooling efficiency and the like of open water cooling of an existing distributing device are solved, a traditional closed cooling mode which can be implemented only by rotating a joint is replaced, and no cooling dead zone exists.

Description

technical field [0001] The invention belongs to the technical field of blast furnace distributor cooling, and relates to a mixed cooling distributor. Background technique [0002] Distributor is an important equipment of bellless top system of blast furnace. Its function is to distribute raw materials evenly into the blast furnace through the rotation and tilting of the distribution chute. The distributor is installed and fixed on the blast furnace throat roof steel ring through the bottom flange of the box body. The bottom of the distributor is located in the inner area of ​​the blast furnace throat, and the bottom of the distributor is in long-term contact with the high-temperature airflow in the furnace. To make the distributor work normally, the distributor must be cooled. The existing distributor cooling method generally adopts open water cooling, that is, it flows from the upper water tank through the cooling pipe to the lower water tank to be discharged. Not only the...
